Thanks for your interest. I mostly learned about this from a friend of mine, and haven't read the articles myself. His first language is English and he's using those insights to learn Mandarin, and even moved from England to Taiwan for that endeavour. I searched for a few keywoards I rememembered from our discussions and found that the Wikipedia page about the Comprehension approach (https://en.wikipedia.org/wiki/Comprehension_approach) looks like a good starting point. Also https://en.wikipedia.org/wiki/Input_hypothesis and https://en.wikipedia.org/wiki/Silent_period

If you decide to read through the research papers linked from the Wikipedia articles (or even if you just read the Wikipedia articles), please feel free to drop me a line for some discussion. My email-address is in my profile.
